铝合金表面环氧涂层中水传输行为的电化学阻抗谱研究
, PP. 544-549
Keywords: 电化学阻抗谱,环氧涂层,水传输
Abstract:
研究了LY12铝合金/环氧涂层电极在不同浓度NaCl溶液中的电化学阻抗谱（EIS），提出了涂层电极在浸泡过程中的不同阻抗模型。通过涂层电容值的变化得出环氧涂层在NaCl溶液中浸泡初期主要发生Fick扩散，中后期发生非Fick扩散。Cl-离子的存在使水的扩散系数增大，但却抑制了水与涂层组元间的相互作用，从而抑制了水的非Fick扩散过程。阻抗参数解析表明。金属/溶液界面的电化学反应阻抗主要决定于涂层中的吸水过程，后者直接决定基体/溶液界面的电化学反应面积。
